Living With Seventeen?!

My name is Yoon Sana. Heard of that surname before? Yup, Im the Kingka group of Pledis High named Seventeen Jeonghan's little sister.
I just returned from New York because i want to live with my brother which is Jeonghan in Seoul.
Jeonghan decide to let me live in his apartment with his other 12 friends.
Will a love story occur while i live in his apartment?
